Storing bedding in the linen cupboard
Short answer: Put it away clean, give it air and avoid plastic bags. Bedding stored airtight for a year comes out with a smell you cannot wash out in one go.
Clean before it goes away
Even bedding that feels clean holds traces of sweat and skin oils. Over the months those turn into yellow marks and a smell. Always wash before packing away.
Air around it
Put it in a cupboard with air, not in a sealed plastic bag. Cotton bags or open baskets work well. See bamboo bedding.
How to keep track
Put a whole set inside one of its own pillowcases. Then the duvet cover, sheet and pillowcase are together and you do not have to search. See bamboo sheets and bamboo pillowcases.
